Definitions

  • the invention relates to a method for producing a workpiece by means of a forming tool.
  • the invention relates to the configuration of a method for producing a defined surface on the workpiece.
  • the WO 01/58615 A1 discloses a method for producing a workpiece having a forming cavity having a forming tool, wherein for forming a surface structure on at least one surface of the forming an at least on one surface profiled embossing element is arranged, the profiling is applied by the forming process on the surface of the workpiece.
  • a workpiece which can be produced according to the invention is, for example, a hybrid component, in particular a fan or guide vane for a gas turbine engine.
  • the component consists for example of a fiber composite material from which a support structure is made whose surface is partially or completely covered with a metal structure.
  • the fan blades of a fan gas turbine engine are exposed to considerable loads by centrifugal forces, gas pressure and vibrations occurring.
  • a metal structure is applied to the surface of the support structure, for example glued.
  • the adhesive bond must be designed so that even consisting of titanium materials metal structure can be securely bonded.
  • the joining surface of the metal structure requires a specific surface structure in order to be able to anchor the bond sufficiently firmly.
  • JP 2004 025273 A Also from the JP 2004 025273 A is a structuring of the tools themselves already known, which generates a surface structure on a workpiece during a forming process.
  • the GB 2 070 486 A shows a structuring of the surface of the tools themselves, which structuring is produced by inserted components, such as balls or rods.
  • the GB 505 358 A deals in general with the application of a surface structure on a metal plate, wherein an embodiment provides that a stamping operation is performed, in which two flat metal plates are pressed against each other, between which a wire mesh is arranged.
  • the invention has for its object to provide a method of the type mentioned above, which is suitable with a simple structure and simple, cost manufacturability, to produce a predetermined surface structure in the workpiece.
  • the workpiece is formed by means of a forming tool.
  • the forming tool has a mold cavity in the usual way, in which the workpiece is formed.
  • the surface of the forming tool can be formed in any desired manner, for example ground and polished, as is known from the prior art.
  • the embossing element is inserted between the workpiece (workpiece blank, not or only partially reshaped) and the forming tool. Due to the forces applied during forming, the profiled surface structure of the embossing element is transferred to the workpiece.
  • the embossing element is designed in the form of a wire mesh.
  • the embossing element can be made, for example, from a highly heat-resistant nickel-based material. Such high-temperature nickel-base materials are offered for example under the name HAYNES 242 or 244 on the market.
  • HAYNES 242 or 244 on the market.
  • the embossing element is made of a heat-resistant material.
  • the choice of materials can be specific to the trainee surface structure of the workpiece done. It is advantageous according to the invention that the embossing element with respect to its structure and its structure can be easily formed and that it is not necessary to produce the surface structure of the workpiece to provide the forming tool with a corresponding surface structure or profiling.
  • it is impractical to produce the forming tools from a highly heat-resistant nickel-based material with a directly introduced fine structure since the fine structure is subject to wear, is very expensive and is very difficult to machine.
  • the method according to the invention is suitable for the production of a wide variety of hybrid components, in which a support structure is connected to a metallic component. Fields of application are not only the fan blades described, but also other elements of a gas turbine engine, and in general, for example, force application elements or the like on any machine or device.
  • the wire thickness moves in a range of 0.1 to 1 mm.
  • the mesh size is between 0.1 to 3 mm.
  • the Fig. 1 shows an upper tool 4 and a lower tool 5 of a forming tool, wherein at least one mold cavity 3 is provided, in which an unillustrated blank of a workpiece 1, 2 (see Fig. 3 ) can be inserted.
  • an embossing element 6 is inserted according to the invention, which is designed as a wire mesh, as in Fig. 2 is shown.
  • the Fig. 3 shows a sectional view of a fan blade 7, which has a support structure 8.
  • This can be formed cell-shaped or honeycomb-shaped.
  • an intermediate layer 9 an upper workpiece 1 and a lower workpiece 2 are glued to the planking.
  • the workpieces 1, 2 are produced by the method according to the invention and, on their side facing the intermediate layer or the support structure 8, have a defined surface structure produced by the embossing element 6.
